Wide feet friendly
Size: 8 Toddler, Color: Tan River Gem
My son has always had extra wide feet and these sandals fit him well. We're limited on what footwear we can buy him and I'm glad I can add these to the list. He hasn't had an issue with these almost causing blisters like other sandals (Teva) we purchased last year. These are lightweight and stylish. I find these perfect for the pool and beach because they dry fast. They're cute enough for daily wear also. I will continue sizing up in these until they no longer have his size.

Great for summer and water but back strap was too big
Size: 8 Toddler, Color: Tan River Gem, Size: 8 Toddler, Color: Tan River Gem
These sandals were okay for my toddler. The sizing was right and the material is great for getting wet. They’re easy to get on and off and they can go with any outfit. The biggest con was that the strap behind the heel is a little too big so that my son’s heel isn’t secured. Every opportunity he got to take them off he would - in the car, on the lawn, at the beach etc. You can tell they weren’t his favorite sandal to wear and were slightly uncomfortable for him. The two Velcro straps on top were great and easy to adjust to his foot. Overall, they get the job done but I probably wouldn’t rebuy them.

Great shoes
Size: 10 Toddler, Color: Tan River Gem
Fantastic sandals! Easy for him to put on and don’t rub his feet even when wet. He loves to wear them anywhere, not just the water and they look great with any outfit. They seem to hold up well and have good traction. I wish they made these in bigger sizes! Definitely worth the money.

Good item
Size: 8 Toddler, Color: Blue River Gem, Size: 8 Toddler, Color: Blue River Gem
I got these Robeez toddler sport sandals for my little one and honestly, they’ve been pretty great overall. The first thing I noticed is how lightweight they are—they don’t seem bulky or heavy at all, which is perfect because my toddler is constantly on the move. They run around, climb, and play hard, and these sandals have held up really well so far. They feel durable enough to handle everyday wear without looking worn out after just a few uses.
Another big plus for me is how easy they are to put on and take off. If you have a toddler, you already know how much of a struggle shoes can be sometimes, so anything that saves time is a win. These slip on pretty easily, which makes getting out the door a lot less stressful.
That said, the sizing was a little off for us. I ordered my child’s usual size, but they do seem to run a bit big. There’s more room than I expected, so they’re not as snug of a fit right now. It’s not a huge issue since they can still wear them, but I probably could have sized down for a better fit.
Overall, I still really like these sandals. They’re comfortable, practical, and hold up well for everyday use. Just keep the sizing in mind when ordering!
